improves ballistic and puncture resistance


Friction between the projectile and fabric has a positive effect on fabric energy absorption by influencing the number of yarn strands that become involved in dispersing the energy [1]. nanoTarge increases the friction between the projectile and fabric through the millions of nanoparticles adhering to the individual fibers; thus increasing the likelihood of more yarn involvement in absorbing the projectile strike.


A 2003 U.S. Army sponsored study determined that the hardness of particles entrained in a Kevlar fabric contribute to the puncture and ballistic resistance. [2] The nanoparticles of nanoTarge are significantly harder than the silica particles used in the study.
